The following is the record of an interview with 4th year CWRU student Kevin Kwock. He’s currently working on his B.S.E. Engineering Physics and music performance degree, B.A. Music – Piano and Harpsichord

1. Can you take me through what research you’ve done/ are currently working on?

I am currently working with Dr. Kash and Dr. Chottiner on a research project regarding crystal ordering in ternary semiconductors. Specifically, ZnSnSb2 has interesting crystal structure near its phase transition temperature;understanding the anion-cation ordering of semiconductors may provide new insights into other families of ternarysemiconductors in the same class. In addition to my university research, some of my previous research has been on studying self-assembling ionic liquids and how we can adapt these unique assembled structures to photonic applications.

The following is the record of an interview with 4th year CWRU student Tori Hamilton. She’s getting ready to graduate with her degree in Sociology:

Can you take me through what research you’ve done/ are currently working on?

Last semester I completed my capstone project titled “Restaurants, Re-Entry, and Recidivism: A Qualitative Analysis of Cleveland’s Re-Entry Programs,” which was a series of interviews I conducted with individuals working on re-entry programs as well as hiring formerly incarcerated people. In total, I interviewed two individuals working in Cleveland for culinary training programs that work with formerly/currently incarcerated individuals, and two employers in the area–one of which runs a restaurant. I looked to better understand the roles that these programs took on, and how they functioned within Cleveland’s community.

Volatility
is the readiness with which a substance

. Excessive volatility often results in the development of pressure within rounds of ammunition and separation of mixtures into their constituents. Volatility affects the chemical composition of the explosive such that a marked reduction in stability may occur, which results in an increase in the danger of handling.

The introduction of

into an explosive is highly undesirable since it reduces the sensitivity, strength, and velocity of detonation of the explosive.

is a measure of a material's moisture-absorbing tendencies. Moisture affects explosives adversely by acting as an inert material that absorbs heat when vaporized, and by acting as a solvent medium that can cause undesired chemical reactions. Sensitivity, strength, and velocity of detonation are reduced by inert materials that reduce the continuity of the explosive mass. When the moisture content evaporates during detonation, cooling occurs, which reduces the temperature of reaction. Stability is also affected by the presence of moisture since moisture promotes decomposition of the explosive and, in addition, causes corrosion of the explosive's metal container.

Explosives considerably differ from one another as to their behavior in the presence of water. Gelatin dynamites containing nitroglycerine have a degree of water resistance. Explosives based on
ammonium nitrate
have little or no water resistance due to the reaction between ammonium nitrate and water, which liberates ammonia, nitrogen dioxide and hydrogen peroxide. In addition, ammonium nitrate is hygroscopic, susceptible to damp, hence the above concerns.

"Green explosives" seek to reduce environment and health impacts. An example of such is the lead-free primary explosive copper(I) 5-nitrotetrazolate, an alternative to

One variety of a green explosive is CDP explosives, whose synthesis does not involve any toxic ingredients, consumes carbon dioxide while detonating and does not release any nitric oxides into the atmosphere when used.
